【摘要】: 目的 比較聲帶息肉、聲帶小結(jié)患者在喉顯微手術(shù)前后的氣流動(dòng)力學(xué)及電聲門圖參數(shù)的變化。分析氣流動(dòng)力學(xué)及電聲門圖參數(shù)之間的相關(guān)性。旨在尋求具有重要臨床意義的指標(biāo)并提供客觀的依據(jù),以了解病變對(duì)發(fā)聲功能影響的程度,評(píng)價(jià)手術(shù)治療的效果。 方法 采用嗓音功能分析儀(AerophoneⅡVoice Function Analyzer)和電聲門圖(DrSpeech Science for windows)對(duì)50例正常人、76例聲帶息肉患者和65例聲帶小結(jié)患者在喉顯微手術(shù)前后進(jìn)行氣流動(dòng)力學(xué)、電聲門圖檢測(cè),對(duì)平均氣流率、口腔壓力、聲門阻力、發(fā)聲效率、基頻微擾、振幅微擾、噪音能量、諧噪比、接觸率、接觸冪、接觸率微擾、接觸冪微擾進(jìn)行分析、比較。采用pearson相關(guān)分析檢測(cè)正常人和患者的平均氣流率與電聲門圖參數(shù)的相關(guān)性。P0.05為差異具有統(tǒng)計(jì)學(xué)意義。 結(jié)果 1、聲帶息肉、聲帶小結(jié)患者的平均氣流率、聲門阻力、發(fā)聲效率均與正常人有顯著性差異(P0.01),聲帶啟、肉患者聲門下壓力與正常人有統(tǒng)計(jì)學(xué)差異(P0.01),聲帶息肉與聲帶小結(jié)患者比較,平均氣流率、聲門下壓力和發(fā)聲效率有顯著性差異(P0.01)。 2、聲帶息肉、聲帶小結(jié)患者的基頻微擾、振幅微擾、噪音能量、諧噪比、接觸率微擾均與正常人有顯著性差異(P0.01),接觸率、接觸冪、接觸冪微擾與正常人無(wú)顯著差異(P0.05)。 3、喉顯微手術(shù)后,聲帶息肉、聲帶小結(jié)患者的平均氣流率、聲門下壓力均不同程度下降,聲門阻力、發(fā)聲效率提高;l微擾、振幅微擾、噪音能量、接觸率微擾均有下降,諧噪比上升。與術(shù)前相比差異有顯著性(P0.01)。 4、聲帶息肉、聲帶小結(jié)患者的平均氣流率與噪音能量、接觸率微擾有正相關(guān)性關(guān)系,與諧噪比呈負(fù)相關(guān),與基頻微擾、振幅微擾、接觸率、接觸冪、接觸冪微擾無(wú)明顯相關(guān)性。 結(jié)論 聲帶息肉、聲帶小結(jié)患者發(fā)聲時(shí)的平均氣流率、聲門下壓力升高,發(fā)聲效率降低,聲帶息肉患者更為顯著。聲帶息肉、聲帶小結(jié)會(huì)導(dǎo)致嗓音質(zhì)量的下降,聲帶振動(dòng)的穩(wěn)定性下降,對(duì)聲帶閉合程度有影響,接觸率、接觸冪、接觸冪微擾對(duì)這兩種疾病的診斷意義不大。通過(guò)喉顯微手術(shù)可以有效的提高患者發(fā)聲的質(zhì)量和效率。氣流動(dòng)力學(xué)和電聲門圖檢查都具有無(wú)創(chuàng)性的特點(diǎn),能對(duì)病變程度進(jìn)行量化,并且兩者在參數(shù)上有一定相關(guān)性,它們與喉鏡檢查相結(jié)合,可以用于嗓音疾病的篩查,療效的評(píng)估和隨訪工作。
[Abstract]:Objective to compare the changes of airflow dynamics and electroglottic parameters before and after laryngeal microsurgery in patients with vocal cord polyps and vocal nodules. The correlation between airflow dynamics and electroacoustic gate parameters is analyzed. The purpose of this study was to find out the important clinical significance and to provide objective basis to understand the influence of pathological changes on vocal function and to evaluate the effect of surgical treatment. Methods 50 normal subjects, 76 patients with vocal cord polyps and 65 patients with vocal cord nodules were treated with Aerophone 鈪,
